Title: Preparing histological sections of non-decalcified bone compact - by impregnating with and embedding in methyl methacrylate, polymerising and sawing
Inventor: EITENMUELLER JUERGEN DR
IPC: G01N1/36
Filed: 1976-09-11
Abstract: Direct prodn. of 20-40 mu thick histological longitudinal and cross sections of non-decalcified bone compacts of man, dog, etc., is effected using Me methacrylate mixed with a catalyst and a plasticiser as impregnating and embedding compsn. for fixed and dehydrated and intermediately treated bone sample. Sections are cut with a micro-circular saw turning at 15000 rpm. The bone sample is first impregnated with Me methacrylate for >=24 hrs. at +4 degrees C. It is then re-impregnated with me methacrylate, mixed with 3-4% benzoyl peroxide and 20-30% nonylphenol-polyglycol ether acetate, at +4 degrees C. The twice-impregnated bone sample is then embedded in a mixt. contg. 4 g. benzoyl peroxide and 0.5 g. polyethylene glycol, having average mol. wt. 1500, for each 100 ml. Me methacrylate. Mixt. is first polymerised 30 mins. at 40 degrees C and left for further polymerisation at 37 degrees C. Block is finally sawn. Polymerised embedding mixt. is pref. further hardened at 60 degrees C, in a warming cabinet. The sections obtd. need no further polishing and can be dyed. Polymer blocks are free from blisters. Sepn. at bone-plastic surface and micro-fractures are prevented. Bone structure can be studied without using specific qualities of light.

Title: Friction spacer between crossing tennis racket strings - controls relative string movement and is of circular or quadratic form
Inventor: KRIEG BENNO PROF DR
IPC: A63B51/11
Filed: 1976-10-08
Abstract: Spacer element (2, 1) of circular or quadratic form, is located by two crossing strings of a tennis or similar ball racket. The spacer which is flat and which is provided with string location grooves, is held in position by the pressure that the string tension produces. The friction coefficient of the spacer material and its contact area with the racket strings governs the amount of relative movement between neighbouring strings. Thus the playing characteristics of a tennis racket can be influenced by the location and type of string spacers.
Patent DE-2646364-A1 (DE)
Title: Temporary dental prostheis moulding in situ - using elastomeric gashet mould sealing round restoration site
Inventor: KENNEDY LELAND T
IPC: A61C5/77
Filed: 1976-10-14
Abstract: A hard positive mould of a patients mouth is taken and the mould is then corrected by adding further hard setting material to restore damaged teeth as required. From this mould a negative flexible mould is obtd. by applying a curable elastomeric material which is allowed to cure while on the positive mould. The negative mould extends beyond the periphery of the positive mould so that when the negative mould is placed in the mouth if forms a gasket seal round the area being restored. When in position in the mouth a vacuum is drawn into the mould via a conduit passing through the mould. If the mould sustains the vacuum this shows that a good seal has been formed and liquid acrylic resin is sucked into the mould where it sets to build up the teeth to the profile of the corrected positive mould. The method is used to cast a temporary dental prosthesis in situ while a permanent attachment is being prepared. The flexible negative mould provides a good seal round the area being restored so that the acrylic resin produces little flash.

Title: Beam interruption smoke detector - has LED's with ring connected power supply arranged round room to focus beams on to central light sensitive receiver
Inventor: HORVATH ZOLTAN
IPC: G01N21/59
Filed: 1977-01-27
Abstract: A number of light emitting diodes (3) is arranged round the periphery of a room or protected area. These are supplied by a ring connected power supply (4) and direct beams on to a single central light sensitive receiver (2).

Title: Sepn. of moisture or other liq. from gas stream - by passing gas along but not through fabric or mesh
Inventor: BRAEUTIGAM MAX
IPC: B01D45/08
Filed: 1977-02-11
Abstract: A method of sepg. liqs. from a gas stream consists of bringing the gas into contact with a fabric or mesh. The gas is conducted along the fabric or mesh, without penetrating through it. Pref., the gas stream is deflected in the vicinity of the mesh, esp. through at least 90 degrees. Used in partic., where a moisture separator is to be incorporated into an already existing plant, as the method does not lead to high flow resistance, cf. where the gas passes through a fabric or mesh.

Title: Embossed consolidated man-made boards - prepd. by wetting board with ammonium hydroxide before embossing
Inventor: CLARKE JOHN T
IPC: B44C1/24
Filed: 1977-03-18
Abstract: In forming a decorative board by depositing fibres onto a surface to form a fibrous mat and compressing this into a consolidated board, improvement comprises wetting the surface of the consolidated board with NH4OH and then embossing at >=400 degrees F/>=1000 psi.

The element also warms the fuel/air mixture.
Patent DE-2733896-A1 (DE)
Title: Single crystal zone melting attachment - with swivelling extension arm controlled by bimetal strip
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/28
Filed: 1977-07-27
Abstract: The parent patent describes a device for the crucible-less zone melting of a semiconductor rod and a support for the holder of the seed crystal. Novelty is that each of the three support arms is articulated. In the position of rest they have the length of a basic arm. Application of heat causes a bimetal strip to release the hinged part and a spiral spring tends to extend the arm in the direction of the rod cone. This creates a better support for very long and thick silicon single crystals, free from dislocations, during a crucible-less zone melting operation.

Title: Quick set cement with good elastoplastic properties - contains bitumen or coal tar in dissolved or emulsion form
IPC: E01C7/26
Filed: 1977-07-29
Abstract: Quick set concrete or mortar is based on (a) a modified Portland cement (CaO)11.(Al2O3)7.CaF2(+C11A7CaF7); an alumina melt cement; Brunauer cement; roman cement (roman lime); Grenoble cement or Portland cement, esp. a gypsum-free Portland cement; (b) chemical quick setting additives; (c) bitumen and/or coal tar in dissolved and/or emulsion form and/or in the milled state and (d) opt. >=1 plastics material in powdered, dissolved or dispersed form (esp. an aq. dispersion). The prods. have rapid setting characteristics and the hardened materials have good elastoplastic properties, similar to those of poured asphalt. The addn. of bitumen or coal tar to the fresh concrete overcomes problems of poor initial strength and reduced mechanical properties encountered when adding plastics materials to cement mixes. Depending on the combination of materials used, the prods. can be used e.g. for road and bridge laying, car parks, garage entrances, sports ground laying and internal flooring.

Title: Railway wagon marshalling system - involves successive movement of part groups both ways over points to obtain desired sequence
Inventor: SCHMITZ WALTER PROF DR ING
IPC: B61J3/00
Filed: 1977-11-08
Abstract: Rail wagons are marshalled by manipulating them over a points crossover so as to form two groups in the first process, one running into a track on each side of the crossover. Next, vehicls are conveyed in groups the opposite way over the crossover, each group being divided into two parts. One part contains the vehicles inside the two groups allotted to the leading part of the sequence, all on one truck, while the other vehicles are collected on the other truck. A third stage involves further alternating moves of the part groups opposite ways, and so on until the prescribed vehicle sequence is attained by alternating collection of vehicles in tracks.

Title: Centrally-controlled telephone exchange - has connection data stored peripherally at sub-control devices and shared control maintaining existing connections
Inventor: FRAAS WOLFGANG ING GRAD
IPC: H04Q3/00
Filed: 1978-04-14
Abstract: The centrally-controlled telephone exchange has the memories that store the stages of a connection assigned individually to the exchange's decentralised subcontrol devices. The switching matrix data describing the course of a connection are stored in the connection memory of that subcontrol device in whose storage area the switching devices that construct the particular connections are located. When the contents of the connection memory are deleted (correctly or incorrectly) all remaining subcontrol devices are caused by a shared control device to maintain existing connections. This means that only a relatively small number of connections are lost if the contents of a connection memory are wrong or inadvertently deleted.
